TRAXXAS Craniac Rear Knuckle Arm Aluminium Upgrade CRA022 by GPM  [CRA022]

CNC-style aluminium rear knuckle for TRAXXAS Craniac

This aluminium rear knuckle arm is an RC-scale replacement part made for the TRAXXAS 1/10 Craniac Monster Truck platform. Supplied as 1pr, the component takes the place of the original rear knuckle arm and is aimed at rear suspension repairs or setup work when a firmer metal mounting point is preferred.

In use the component locates the rear wheel hub and transfers suspension loads and steering inputs into the axle and link points. Compared with stock plastic pieces it provides a stiffer mounting surface, which can change steering feedback and rear traction under load. After fitting, check camber, toe and link geometry to ensure handling stays as intended.

Fitment follows common replacement steps for RC knuckle arms: remove the wheel and hub, unbolt the factory knuckle arm, swap in the aluminium unit in the same orientation and secure with the original fasteners. Confirm free hub rotation and correct drive alignment before operating the truck.

Choose this aluminium rear knuckle arm when you need a tougher aftermarket option for rear-end tuning or repair on the TRAXXAS 1/10 Craniac, and always verify fitment and fastener torque after installation.
